The present invention generally relates to spa devices, components, and systems. More specifically, the present invention is directed to an improved bearing and shaft assembly for jet assemblies, to a jet assembly that includes the improved bearing and shaft assembly, to a pump, such as a magnetic coupling-type pump, comprising a motor assembly and a jet assembly that includes the improved bearing and shaft assembly, and to a method for dispensing a fluid using the improved bearing and shaft assembly.
Spa devices, components, and systems are known in the art. Spa devices are used in commercial and recreational settings for hydrotherapy, massage, stimulation, pedicure, and bathing purposes. Typical spa devices include a motor that drives a pump to circulate water from the spa device. In particular, a shaft of the motor is used to directly mount an impeller, which is then used to circulate water into and out of the spa device. Since the motor may not operate wet, a seal or a series of seals may be required to prevent water from entering the motor. The seals will wear to the point where water will enter the motor and consequently, the entering water may cause the motor to burn out. At this point, the motor assembly may be replaced in order to continue operation. This is expensive and may take several hours in which to perform.
Additionally, because typical spa devices have extensive piping systems that are built into the spa device to transport water, the spa devices are traditionally difficult to clean. This results in downtime and complicated maintenance schedules to clean such spa devices. Furthermore, if a spa device has a light source associated with it, to replace or repair such a light source can be time consuming and complicated when the light source is not easily accessible.
In the spa application environment, water is commonly added with certain substances and/or products, such as salt, chemicals, sand, massage lotions, etc. Due to this fact, traditional bearings, such as ball bearings and metal bushings, will not be suitable for a long term and reliable operation. The presence of chemicals and sand, for example, will cause some or many currently available bearings to wear out quicker than normal and result in pump failures.
In addition, for magnetic coupling-type pumps, it is almost impossible to have a perfect alignment between the motor shaft axis and the impeller rotation axis. The imperfect alignment or misalignment will result in high vibration noise.
The present invention overcomes one or more of the shortcomings of the above described spa devices, components, and systems. The Applicant is unaware of inventions or patents, taken either singly or in combination, which are seen to describe the present invention as claimed.
In one exemplary aspect, the present invention is directed to an improved bearing and shaft assembly for jet assemblies. The improved bearing and shaft assembly comprises a bearing assembly comprising an outer bearing member and an inner bearing member, and a shaft assembly comprising a shaft member, a shaft protection member, and a locking mechanism.
The outer bearing member preferably comprises a ring-like base and a cylindrical body extending upwardly from the ring-like base. The cylindrical body comprises a first end, a second end, and a cavity extending from the first end to the second end. The cavity is dimensioned and configured for receiving the inner bearing member. The outer bearing member is dimensioned and configured for fitting within a cavity of an impeller of a jet assembly.

The cavity of the cylindrical body of the inner bearing member is dimensioned and configured for receiving the shaft member and shaft protection member of the shaft assembly.
The shaft member comprises a base and a cylindrical body extending upwardly from the base of the shaft member. The cylindrical body of the shaft member comprises a first end and a second end. The shaft member is adapted for being secured within a housing of a jet assembly, such as the base of the shaft member being secured centrally within a cavity of the housing of the jet assembly.

The outer bearing member 120 includes an inner surface 121, an outer surface 123, a base 122, preferably a ring-like base, and a cylindrical body 124 extending upwardly from the ring-like base 122. The ring-like base 122 has a predetermined thickness. The cylindrical body 124 has a first end 126, a second end 128, and a cavity 129 extending from the first end 126 to the second end 128. As shown in
The inner bearing member 130 includes an inner surface 131, an outer surface 132, and a cylindrical body 134 having first end 136, a second end 138, and a cavity 139 extending from the first end 136 to the second end 138. As shown in

Referring to
In addition to the improved bearing and shaft assembly 100, the jet assembly 180 further includes a housing 181 and an impeller 170 (as described above), preferably a magnetic impeller and more preferably a planar magnetic impeller.
As shown in
The magnetic impeller 170 is adapted for being positioned within the cavity 184 of the housing 181 and configured to rotate within the cavity 184 when a magnetic pole array 210 from the motor assembly 200 is driven such that rotation of the magnetic impeller 170 causes the fluid to flow into the inlet aperture 185 and out the outlet aperture 186.
Preferably when in use and as shown in
Moreover, during operation of the motor assembly 200 as shown in
Referring to
As best shown in
In that regard, the motor assembly 200 may include and/or be coupled to a power source (not shown) that enables rotation of the motor shaft member 208. Upon operation of the motor assembly 200, the motor shaft member 208 is rotated such that the magnetic field 212 generated by the magnetic pole array 210 moves or fluctuates in accordance with the rotation of the magnetic pole array 210.
In addition, when the magnetic coupling-type pump 300 is assembled, the jet assembly 180 is positioned adjacent or in close proximity to the mounting housing member 206 of the motor assembly 200. The jet assembly 180 is preferably magnetically coupled to the motor assembly 200 when the jet assembly 180 is positioned adjacent or in close proximity to the mounting housing member 206. The jet assembly 180 and mounting housing member 206 can be secured or coupled to one another by any method and/or device known to one of ordinary skill in the art.
Furthermore, the motor assembly 200 may further include an air channel (not shown), or air channel member (not shown). In that regard, the air channel includes an inlet (not shown) and outlet (not shown). The air channel, in part, enables the jet assembly 180 to produce a jet stream of fluid that includes an air mixture.
Additionally, the motor assembly 200 may further include sensors (not shown). The sensors may be positioned on a front facing surface (not shown), or annular flange, of the mounting housing member 206. The sensors may include electrodes that act as level sensors that sense the level of fluid around the pump 300. If the sensors detect that the level of fluid around the pump 300 is below a predetermined level or value, then the sensors can shut off the pump 300. For example, if pump 300 is being used in a spa application, the sensors can detect the level of fluid in a basin in which the pump 300 is being used. If the fluid level is too low such that continued operation of pump 300 may cause damage to the pump, then sensors send a signal to motor assembly 200 to stop the motor assembly 200 from operating. Therefore, the sensors act as a safety mechanism that prevents the pump 300 from burning out if fluid levels are too low for proper functioning of pump 300.
Although the sensors have been described as being associated with particular aspects of motor assembly 200, it is contemplated that sensors can be associated with other and/or additional portions of motor assembly 200. Additionally, in other embodiments sensors can be associated with jet assembly 180. Furthermore, in other embodiments sensors can be associated with both motor assembly 200 and jet assembly 180. Moreover, although two sensors are shown it is contemplated that one sensor or more than two sensors can be used to detect fluid levels around pump 300.
In a further exemplary aspect, the present invention is directed to a method for dispensing a fluid using an improved bearing and shaft assembly 100 for a jet assembly 180, the method comprising the steps of:
